Like cost of bordering a park with flower beds, length of lace required to decorate a table cloth, etc. Stuff that we may encounter in our day to day life. In this topic we’ll practice more of real world problems. So far we practiced simple and straight forward problems of finding perimeter or area.
Real world problems: This is the most important topic for this chapter. As in case of squares and rectangles, problems pertaining to calculating costs, area of borders and irregular shapes are also included. I have included problems that require us to use both the common approximate values of.
Circles : This is a completely new topic for 7 th Both area and circumference of a circle involve the use of the constant. As before problems of finding dimensions from given area are also there to test your grip on the topic. Here I have included some irregular shapes as well. Triangles and parallelograms : This topic covers practice questions based on perimeter and area of triangles and parallelograms. There are problems of finding border areas as well. Problems pertaining to costing are also included. I have incorporated various types of problems such as finding perimeter and area from given dimensions and also finding dimensions from given perimeter and area. This topic is a mere extension of what was learned in class 6. This worksheet has larger numbers than the worksheet above and not all sides are labeled. Squares and rectangles : The first topic under this chapter deals with practicing problems related to perimeter and area of squares and rectangles. Perimeter Polygons 2 (Intermediate) Find the perimeter by adding the length of the sides of each polygon. We’ll be practicing calculating perimeters and areas of various basic geometrical shapes.
